Grays Harbor Public Utility District Taps Exalt for Network Backhaul

Washington public utility deploys Exalt microwave backhaul systems to transport SCADA, AMR traffic

CAMPBELL, Calif., July 19, 2011 – Exalt Communications today announced that Grays Harbor Public Utility District (GHPUD), a public utility based in Aberdeen, Washington has deployed Exalt microwave backhaul systems to carry critical SCADA and automated meter reading (AMR) traffic from its substations to its main data center. GHPUD provides electrical service to customers in northwestern Washington, and its network also carries two-way radio and 911 voice traffic for Grays Harbor county agencies and Ethernet traffic for Internet service providers.

GHPUD uses a combination of fiber and microwave to link its 22 substations with its main data center. While microwave systems have been in use at GHPUD for a decade or more, the District’s technical staff was having reliability problems with legacy microwave systems at eight of the substations. The GHPUD team selected Exalt microwave systems not only for their high reliability but also because the Exalt systems can carry both native TDM and IP traffic.

“Our operations depend on the reliable flow of information throughout our network, and we wanted microwave backhaul systems that we could deploy and depend on,” said Mark Forsman, communications foreman at GHPUD. “The Exalt systems have been totally reliable in all weather conditions – they just keep running, day in and day out.”

As configured for GHPUD, the Exalt systems carry 100 megabits per second (Mbps) of Ethernet traffic and up to 11 T1 lines. While the amount of IP traffic on the network is relatively small at this point, the Exalt systems offer plenty of scalability for new applications and traffic over time.
